چکیده
We consider a two-tile reconfigurable intelligent surface (RIS) assisted wireless network with two-antenna transmitter and receiver over Rayleigh fading. show that the average received signal-to-noise-ratio (SNR) optimal combining transmission vectors are given by left right singular spaces of RIS-receiver transmit-RIS channel matrices, respectively. Moreover, phases at two tiles RIS determined elements latter spaces. To further study effect phase compensation, we statistically characterize SNR all possible combinations directions pertaining to deriving novel expressions for outage probability throughput each those modes. Furthermore, comparison, derive corresponding in absence RIS. Our results an approximate improvement 2 dB due compensation

Performance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...

Visible light communications (VLC) for car-to-car (C2C) communications is an alternative and complementary solution to the radio frequency based C2C especially in high vehicle density environments. In this paper, a mathematical model for C2C VLC system under different communication geometries is presented. A market-weighted headlamp beam pattern model is employed. Both line-of-sight and non-lin...

متن کاملPerformance Analysis of SVD-assisted Downlink Multiuser MIMO Systems
Abstract: Multiuser multiple-input multiple-output (MIMO) downlink (DL) transmission schemes experience both multiuser interference as well as inter-antenna interference. Instead of treating all the users jointly as in zero-forcing (ZF) multiuser transmission techniques, the investigated singular value decomposition (SVD) assisted DL multiuser MIMO system takes the individual user’s channel cha...
متن کاملHigh-Rate Space Coding for Reconfigurable 2× 2 Millimeter-Wave MIMO Systems
Millimeter-wave links are of a line-of-sight nature. Hence, multiple-input multiple-output (MIMO) systems operating in the millimeter-wave band may not achieve full spatial diversity or multiplexing. In this paper, we utilize reconfigurable antennas and the high antenna directivity in the millimeterwave band to propose a rate-two space coding design for 2 × 2 MIMO systems. The proposed scheme c...
